2.5 Wireless LAN Device
This section describes the wireless LAN Access Point (AP) and mobile stations that can be
connected with the OfficeServ 7400 system. Two types of AP are available: the WBS24
(Combo), connected via the 4WLI card, and the WBS24 (Basic), connected via the MGI
card.
2.5.1 Wireless LAN Base Station (Combo and Basic)
The WBS24 consists of a wired processing component and wireless processing component. The
wired processing component has an IEEE 802.3 Ethernet interface connected to the LAN. The
wireless processing component has 2.4 GHz frequency bandwidth of wireless LAN, which com-
plies with the RF interface based on the IEEE 802.11b standard.
Figure 2.23 WBS24
The wired Ethernet interface is connected with the LAN based on 10/100 BASE-T and trans-
mits/receives data (e.g., Internet access) other than voices. The wireless processing component
transmits/receives voice data for wireless voice calls and accesses the wireless Internet. The
maximum transmission speed on the wireless component is 3~4 Mbps. Several users can simulta-
neously access the wireless Internet using a WBS24.
2.5.2 Mobile Station
The mobile phone WIP-5000M (wireless IP-Phone mobile type) uses IEEE802.11b
wireless LAN to allow users to make voice calls. The phone performs the wireless IP
function by compressing voice (Voice over WLAN) and transmitting as data packets. It sup-
ports hand-over when moving between Access Points (WBS24). Data terminals such as
PDAs and laptop PCs that support wireless connection can be used along with the WIP-
5000M. The WIP-5000M also performs the message service functions supported by the Of-
ficeServ 7400 system.
